3 Claims.

The present invention relates to new and useful improvements in toolsfor removing insulators from electric fences and from other places towhich the insulator may be attached, the primary object of the presentinvention being to provide a tool of this character adapted for engagingand removing the nail employed for holding the insulator in positionwithout danger of breaking the insulator.

A further object of the invention is to provide a tool of this characterof simple and practical construction, which is strong and durable,efficient and reliable in performance, relatively inexpensive tomanufacture and otherwise well adapted for the purposes for which thesame is intended. 7

Other objects and advantages reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming part hereof, wherein likenumerals refer to like parts throughout and in which:

Figure 1 is a side elevational view,

Figure 2 is a top plan view.

Figure 3 is a front elevational view.

Figure 4 is a Vertical sectional view taken substantially on a line 4-4of Figure 2.

Figure 5 is a perspective view of the wire jaw employed for engaging oneside of the nail, and

Figures 6 and 7 are top plan view of modified forms of base membersadapted for engaging insulators of various shapes.

Referring now to the drawings in detail andv with particular referenceto Figures 1 to 5, inclusive, the numeral 5 designates a base mem herhaving an opening 6 therein adapted for receiving the insulator l ofconventional construction, which is usually secured to a supportingstructure by a nail 8 under the head 9 of which a washer i ispositioned.

A post ll rises from the base adjacent its rear end, the underside ofthe base immediately beneath the post having a spur l2 formed thereonadapted to bite into the work to prevent slipping of the base duringoperation. Projecting from the rear of the base beyond the post I! is aheel portion [3. i

The upper end of the post H terminates in spaced upstanding ears I4having a pin extending therebetween and freely positioned in an edge [9adapted for engagement under the head 9 of the nail.

A second handle member 20 has its front end bifurcated as shown at 2!for receiving the lower edge of the handle member Fl for pivotallymounting the same thereon by means of a trans verse pin 22. The frontend of the handle 20 extends angularly as shown at 23 forwardly of thepivot 22' and the furcations thereof are formed with openings 24 adaptedto receive the inturned ends 25 of a U-shaped wire member 26, the biteportion of the'wire member having a jaw v21 mounted thereon formed witha knife edge 28 of arcuate shape and adapted to engage the nail underthe head thereof at a side opposite from the jaw l8. The edge of the jawopposite from the blade 28 may be formed with a flat fingergripextension 29 to guide the jaw into its-position for engaging under thehead 9 of the nail.

' In Figures 6 and '7 of the drawings, I have illustrated modified formsof base members, Figure 6 representing a base 361 having a curved yoke3| for engaging the insulator while the base 32,. shown in Figure 7 ofthe drawings, is provided with a U-shaped yoke 33 having its sidesdisposed in parallelism and adapted for engaging an insulator ofcomplementary shape.

In the operation of the device the jaws l8 and 21 are adapted to engageunder the head of the nail and upon an upward movement of the handle 20relative to the handle I7, the jaw 21 will be pulled rearwardly to rideunder the head 9 therebyloosening the nail, and upon exerting a downwardpressure on the handle I! the nail will be raised upwardly and removedfrom the insulator. During the downward movement of the handle I! thesame is also urged forwardly so that the pin [5 will travel along theslot I6 and thuskeep the jaw l8 in the plane of the axis of the nail toprevent bending of the nail and eliminate danger of cracking or breakingthe insulator.

It is believed the details of construction and manner of use of thedevice will be readily understood from the foregoing without furtherdetailed explanation. 1

Having thus described the invention what I claim is:

1. A nail puller comprising a base, a handle pivoted on the base, andhaving a jaw adapted to engage under the head of the nail at one sidethereof, a handle pivoted to the first-named handle, and a jaw pivotallyattached to the second-named handle and adapted for movement under thehead of the nail at a side thereof opposite from the first-named jawupon a predetermined movement of the second named handle.

2. A nail puller comprising a base, a handle pivoted on the base, andhaving a jaw adapted to engage under the head of the nail at one sidethereof, a handle pivoted to the first-named handle, a U-shaped wiremember having its ends attached to the .second-namedhanfle. and a secondJaw carried at the bight portion of the member and adapted for engagingunder the head of the nail at a side thereof opposite from the firstjaw.

3. A nail puller comprising a base, a pair of handles, a pin and slotpivotal connection between one handle and the base providing abackand-forth movement for the handle, the other handle being pivoted tothe first-named handle. and jaws carried by said handles and adapted toengage under the head of the nail at opposite 10 sides thereof.
